Klein Tools VDV500-820 Cable Tracer with Probe Tone Pro Kit for Telephone, Internet, Video, Data and Communications Cables

Worked perfectly. Seems pretty sturdy

Im a locksmith and sometimes my clients dont know where the power for their locking hardware is. This I can just hook to a wire and listen for the tone. Then either it leads me to where the power is or we find out their hardware stopped because of it shorting and all of the wires are making weak tones.

Ive used it a few times so far and it hasnt disappointed. Works great

Great for use all klein tools i recommend when doing electrical

We bought a large new to us home that had dozens of unlabeled low voltage runs - cat6, speaker and coax. Within a few hours, I was able to sort out and label everything with this device. Very easy to use and find wires buried in walls.

If using jack you will never find your cable. The tone produced is quiet and continuous but can only be heard when you’re within 2 inches of the pack making the tone.

Purchased to trace some wires and it worked very well.

As you can see from the photo I had a mess to figure out. This tool contributed zero to trace these wires. I probably wasn’t using the tool properly. I ended up tracing voltage the old way to gets all these circuits to work properly.

Instructions not clear, but it’s a great product for tracing wires. It is great with 120volt wires, but make sure power is off to circuit. It is confusing because it says only use on 60volt and under and 20 volt and under for energized wires.

This unit will only trace out open ended wires. if youre trying to trace something connected it will not give a signal. But other than that its a nice unit.
